How did Babasaheb Tarkhad's reaction to forgetting the Naivedya demonstrate the depth of his repentance?

Babasaheb Tarkhad's reaction powerfully demonstrates deep and sincere repentance. When he realized his mistake, he didn't just feel a fleeting sense of guilt. Chapter 9 describes a profound emotional and spiritual crisis. He was "filled with remorse" and spoke to Sai's image with "tearful eyes," elevating his forgetfulness from a simple mistake to a "great sin" for which he had reached "great repentance." His feeling of being "shameless" and his immediate prostration at the photograph's feet show his humility. Crucially, he took action by writing a letter to his son hundreds of miles away in Shirdi, pleading for him to ask for Sai's forgiveness, which shows he believed in Baba's omniscience and felt an urgent need for divine mercy.
